Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.

shipper is a power distribution tool for developers with multiple projects who do frequent releases. It automates the tedious process of shipping a software release and (if desired) templating a project Web page. It can deliver releases in correct form to SourceForge, Berlios, and Savannah, and knows how to post a release announcement to freecode.com via freecode-submit.

BitRock InstallBuilder allows you to create
easy-to-use multiplatform installers for Linux
(x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.

Launch4j is a cross-platform tool for wrapping
Java applications distributed as jars in Windows
native executables. The executable can be
configured to search for a certain JRE version or
use a bundled one, and it's possible to set
runtime options, like the initial/max heap size.
The wrapper also provides better user experience
through an application icon, a native pre-JRE
splash screen, and a Java download page in case the appropriate JRE cannot
be found. The increase in size of the application
is small.

Slackpkg is an automated package-management tool for Slackware Linux. It can do tasks such as automatic downloading and installing or upgrading, browse the MANIFEST.gz (Slackware package-contents guide), and more. Dependencies are not automatically handled. It is not a replacement for pkgtool, but a valuable add-on.

freecode-submit performs remote submissions of release updates to Freecode via its JSON API. It is intended for use in project release scripts. It reads the metadata from an RFC-2822-like message on standard input, possibly with overrides by commandline switches. It supersedes freshmeat-submit, which no longer works following the site name change.

magicErmine is a tool for creating portable applications for Linux. It allows the same Linux executable to be run on a wide range of different distributions.
Like statifier, It makes one executable file with no run-time dependencies from a dynamically linked
executable and all of its libraries. Unlike
statifier, it is able to add arbitrary files to
the packed executable, such as configuration files or pixmaps.
